Basics Subwoofer Balance Control - 18

Subwoofer Balance Control

With external speakers attached, the subwoofer functions as a bass speaker to augment the stereo sound. Without external speakers, the subwoofer produces full-range sound instead of just bass.

Subwoofer Internal

Basics Subwoofer Balance Control - 19

Adjust the subwoofer balance using the subwoofer balance control. The subwoofer balance control only works with external speakers attached. To increase or decrease the bass coming from the subwoofer in relation to the sound coming from the external speakers, adjust the subwoofer balance control.


Basics TV/FM Radio Tuner Card - 20

TV/FM Radio Tuner Card

The TV/FM radio tuner card turns the computer into a television and FM radio receiver, complete with remote control. An expansion ribbon connector for the optional TV/FM radio tuner card provides NTSC and PAL input from an external TV antenna or cable. Change channels by typing the channel number on the keyboard or with the remote control. Switch between the current and previous channel by pressing the Tab key. The computer displays the user-assigned channel name on the picture in the video window.

Apple Video Player software supports the TV/FM tuner card. The user can disable channels and require a password to access the disabled channels. Users can also capture or freeze a single frame of video or record a segment of video as a QuickTime movie. It isn’t possible to resize the window while recording a movie.


The TV picture is in its own window on the desktop, and the default size of the window is 320x240 pixels. The picture can be resized from 160x120 pixels up to 640x480 pixels. The resolution of the picture does not increase at larger window sizes, but the image is expanded by doubling the pixel size or by two-dimensional linear interpolation.

The TV signal is carried in YUV format for improved picture clarity. The YUV format is 16-bit, with 8 bits for the Y (luminance) channel and 8 bits for the U and V (chrominance) channels to share by multiplexing. The picture is clearer because the YUV format carries more levels of luminance information.


The card is available in versions for NTSC, PAL, and SECAM television systems. The features of the TV tuner include the following:• Remote tuner for 181 broadcast and cable channels (U.S.

version)• Coaxial connector for TV antenna or cable input (F-type

connector in U.S. and Japanese version, IEC-type connector in Europe)

• TV picture in a resizable and movable window• YUV format for improved clarity• Closed captioning and teletext support• Software password protection• Automatic and manual channel programming• Single remote control for TV and for playback of audio

CDs


The features of the FM radio tuner include the following:• FM radio frequencies received and displayed• Stations scanned and searched up and down the frequency

spectrum• Step frequency• DX mode to tune out harmonic spillover from other

stations• Stereo/mono station indicator• Preset station programming

Basics Digital Audio Video (DAV) Technology - 24

Digital Audio Video (DAV) Technology

The optional video input card has a separate connector called the DAV connector. The DAV connector provides access from a PCI card to the video input card by means of a 60-pin cable. This allows the PCI expansion card to use the video card to transfer real-time video data to the computer. The video card accepts video from an external source and displays it in a window on the computer’s monitor.

Note:

The interface of the 60-pin DAV connector is a superset of the interface on the 34-pin DVA connector on the Power Macintosh 5200, Power Macintosh 6200, and Quadra 630 computers. An adapter cable is provided with the Performa 6400 video-in cards to connect 34-pin DVA compatible cards developed for the Power Macintosh 5200 and 6200 computers to the new 60-pin DAV connector.

Basics Digital Audio Video (DAV) Technology - 25

Note:

The DAV connector on the video input card provides some of the functionality of the DAV connectors found on the Power Macintosh 7100 and 8100 models, and the Macintosh Quadra AV models, but it is not compatible with any of those connectors.

Basics Sound - 26

Sound

The sound system supports 8-bit and 16-bit stereo sound output and input. It can create sounds digitally and play the sounds through the internal speakers or send the sound signals through the sound output jacks.

Digitizing Sound

The 6400 and 6500 computers digitize and records sound as 16-bit samples. It can use two of these sampling rates—11k, 22k, or 44k samples per second. It can record sound from the following sources:• Built-in microphone• Microphone connected to the sound input jack• Video input module• Compact disc in the CD-ROM player

Basics Sound - 27

Sound Output

The 6400 and 6500 computers have one built-in speaker/subwoofer and two sound output jacks, one on the front and one on the back. Both output jacks are connected to the sound amplifier. Inserting a plug into either jack disconnects the internal speakers. The jack on the front is intended for headphones, and the jack on the back is intended for external speakers. The rear jack is muted when headphones are plugged in the front jack.

Basics Sound - 28

Sound Input

One sound input port for stereo sound input supports the Apple PlainTalk Microphone, and it supports non-Apple microphones. It also supports a standard stereo (miniplug-to-RCA) cable adapter for connecting stereo equipment to the computer.

Note:

The sound input port does

not

support the Apple Omni microphone (the round microphone shipped with some earlier Macintosh models) or the attenuated RCA adapter provided with some models of Macintosh.

Basics Expansion Bay - 29

Expansion Bay

The expansion bay includes audio, data, and power connectors for adding a SCSI CD-ROM or other SCSI device. The bay is configured for 5.25-inch devices, but with modification to the carrier, a 3.5-inch SCSI device could be installed. In some computers, the bay may already be occupied by a Zip drive.

Basics Expansion Bay - 30

Chassis Revision Identification

There are two versions of the Metal Chassis Assembly for the Power Macintosh/Performa 6400 and 6500 series machines. Part number 922-2272 Chassis, Metal, Rev. A should be used for all Power Macintosh/Performa 6400 series machines with the exception of the PM/Perf 6400/200 with Zip Drive. Part number 922-2707 Chassis, Metal, Rev. B should be used for all Power Macintosh 6500 series machine as well as the PM/Perf 6400/200 with Zip Drive.

Basics Intelligent Device Electronics (IDE) Hard Drive - 31

Intelligent Device Electronics (IDE) Hard Drive

The internal hard drive uses IDE technology, commonly used in DOS-compatible systems, and the standard ATA-2 or IDE interface. The hard drive has a standard 40-pin ATA connector, and a separate 4-pin power connector.

The IDE hard drive functions the same as a typical SCSI hard drive. You must replace IDE drives like for like. The IDE drive does not affect SCSI ID selections or SCSI termination schemes. Six external SCSI devices may be daisy-chained through the external SCSI port.

Basics Peripheral Component Interconnect (PCI) Technology - 32

Peripheral Component Interconnect (PCI) Technology

The 6400 and 6500 computers offer a peripheral component interconnect (PCI) expansion bus. Because the PCI bus is an industry standard, most existing PCI 2.0-compliant cards (with the addition of a Macintosh OS-specific software driver) will work in these computers.

PCI offers significantly higher performance than the NuBus architecture used in previous Macintosh models. Running at 33 MHz, the PCI bus is up to three times faster than NuBus, offering overall enhanced system performance, particularly in the areas of video and networking.

Basics Peripheral Component Interconnect (PCI) Technology - 33

Note:

PCI expansion slots are compatible with all PCI 2.0 specification-compliant cards with the addition of Macintosh-OS-specific software driver. Nubus cards

cannot

be used in this expansion slot. PDS cards for the Macintosh LC family, the Macintosh Quadra 630 computer, or cards that operate in the I/O expansion slot in Power Macintosh 5200 and 6200 computers are

not

compatible with the PCI expansion slots.

Basics Communications - 34

Communications

The logic board has a communications slot for adding a communications module without occupying the PCI expansion slots. The slot uses a PCI bus, and supports the following cards:• 10Base-T (twisted pair) Ethernet card• 10Base-2 (thin coax) Ethernet card• AAUI (Apple standard) Ethernet card• 28.8 bps fax/data modem card

Note:

This PCI bus-compatible slot is

not

compatible with communications cards for the Macintosh LC family and Macintosh Quadra 630 or with cards that operate in the Power Macintosh 5200 and 6200 communication slots. The exception is that cards that do not use the bus, such as serial modem cards, have been designed to work in either type of communications slot.

Basics Modems - 35

Modems

Some Performa 6400/180 and 6400/200 computers shipped with internal GeoPort modems and some with internal Global Village modems. If the modem isn’t replaced like-for-like, the communications software is incompatible with the modem.

To identify the modem originally shipped in the computer look at the last three characters of the serial number to compare with characters found in this table.

Modem 6400/180 6400/200

Global Village Platinum 7U7 836

GeoPort 95R 95S

Basics Modems - 36

GeoPort Technology

Geoport is a hardware and software communications architecture that has been optimized for computer-telephony integration. It has three main attributes:• It lets any GeoPort-compatible computer connect to any

telephone (analog or digital, public or private) anywhere in the world.

• Once connected, it supports an arbitrary number of independent data streams up to a total bandwidth of 2 MB/second.

• Unlike traditional asynchronous data communications (such as AppleTalk), GeoPort also supports isochronous data streams (such as real-time voice and video) and provides the real-time Application Program Interfaces (APIs) necessary to hide the implementation details from both the recipient and the sender.

Basics Dual In-Line Memory Modules (DIMMs) - 37

Dual In-Line Memory Modules (DIMMs)

The 6400 and 6500 come with 16 MB of DRAM. Two 168-pin sockets allow for memory expansion.

The 6400 and 6500 use DRAM Dual In-Line Memory Modules (DIMMs) instead of DRAM Single In-Line Memory Modules (SIMMs). Whereas SIMMs have 72 pins, DIMMs have 168 pins. The extra pins provide a 64-bit data path, compared to a 32-bit data path for SIMMs.


Important:

The SIMMs used in previous Macintosh models are

not

compatible with the 6400 or 6500. For the Performa 6400, use 168-pin, fast-paged, 70 ns or faster, 2K refresh rate DIMMs. For the Power Macintosh 6400, use 168-pin extended data out (EDO) mode, 60 ns or faster, and 1K or 2K refresh count. For the Power Macintosh 6500, use 168-pin, 5-volt buffered extended data out (EDO) mode, 60 ns or faster, 2K refresh rate DIMMs. Do

not

use DIMMs with a 4K refresh count.

Also, the JEDEC MO-161 specification shows three possible heights for the 8-byte DIMM. For these computers, use only the shortest of the three (1.100 inches). Taller DIMMs put excessive pressure on the DIMM sockets due to mechanical pressure inside the case.


Performa/Power Macintosh 6400

DRAM DIMMs can be installed individually. However, if you wish to take advantage of the computer’s interleaving capability, which provides maximum performance, you must install the DIMMs in matching pairs.

Memory interleaving allows the computer to read or write to its memory while other memory reads or writes are occurring, thus providing for faster performance.

Note:

DIMMs purchased from different manufacturers can be paired as long as they are the same size and speed.



The 8-byte DIMMs can be installed one or more at a time. The logic board supports only linear memory organization, and no performance gains result when two DIMMs of the same size are installed. Any supported size DIMM can be installed in either DIMM slot, and the combined memory of all installed DIMMs is configured as a contiguous array of memory.

The DIMM slots accommodate 168-pin, 5-volt, fast-paged and EDO DRAM DIMMs. The largest DIMM supported is a two-bank DIMM holding 64 MB.

Note:

The logic board does

not

support 3.3-volt EDO DIMMs. These DIMMs don’t mechanically fit into the DIMM slots.

Basics Cache Expansion - 41

Cache Expansion

The optional 256K (512K for the 6500/275 and 6500/300) level-2 cache is on a 160-pin DIMM card that plugs into a 160-pin edge connector on the logic board and includes an integrated cache controller.

Note:

Apple does

not

support third-party cache cards for these computer models. The 160-pin cache expansion slot is

not

compatible with cache cards for previously released Power Macintosh computer models.

Basics 6500 Supported Monitor Resolutions - 42

6500 Supported Monitor Resolutions

The system software on Power Macintosh 6500 computers allows selecting monitor resolutions above 1152 x 870. But these higher resolutions cause poor video output, such as misaligned or skewed video, low brightness, and so on.

Monitors connected to Power Macintosh 6500 computers should not be set to resolutions above 1152 x 870. Check the Monitors and Sound Control Panel to make sure the resolution is set to 1152 x 870 or below.

EDO-Compatible Logic Board Identification

Before you install extended data out (EDO) memory in a Performa or Power Macintosh 6400 computer, you must verify that the logic board is EDO-compatible.

There are four ways to verify that a logic board from a Performa or Power Macintosh 6400 computer is compatible with EDO memory:• The logic board is the original board that shipped in a

Macintosh Performa 6400 equipped with an internal Zip drive

• The logic board has soldered-on EDO DRAM• The logic board has a resistor present at chip U34• The logic board has

no

resistor present at location R77

The details for identifying an EDO-compatible logic board by these methods are presented in the following sections.


Performa 6400 with Zip Drive

If a Macintosh Performa 6400 included an internal Iomega Zip drive, the logic board shipped in the computer supports EDO memory.

Zip Drive


Soldered-On DRAM is EDO

6500—Distinguishing Video Jitter from Blur

Service providers may encounter two slightly different video symptoms on monitors connected to Power Macintosh 6500 computers. The first step in troubleshooting this issue is to differentiate video jitter from blurry video. There is a different solution to each of these conditions.

Video jitter affects monitors connected to models having a 225 or 250 MHz logic board. Jitter is evident at the edges of the screen or windows and dialog boxes where the pixels shimmer or jump.

Blurry video is seen as a fuzzy image over the entire screen on monitors set to resolutions of 832 x 624 and higher.


Power Macintosh 6500 computers falling within the following serial number ranges may have these video issues.

Video Jitter:

PM 6500 from XB708xxxxx to XB718xxxxx

Blurry Video:



Video Jitter Solution

If you identified a video jitter symptom, you need to inspect the logic board to distinguish a reworked board from a board that hasn’t been reworked. Apple has reworked 225 MHz (P/N 661-1322) and 250 MHz (P/N 661-1332) logic boards.

1 Remove the logic board.

2 Look at the resistor located at R-363 on the bottom of the board.

R 363R 363


3 You may need to use a magnifying glass to see the print on this resistor.

If 100 is printed on the resistor, the board has not been reworked.

If 101 is printed on the resistor, the board has been reworked.

4 Replace a board that has not been reworked with a reworked logic board.

R 363R 363

Additional Procedures Blurry Video Solution - 13

Blurry Video Solution

If you identified a blurry video symptom, you need to inspect the audio/monitor connection subassembly.

1 Remove the audio/monitor connection subassembly from the computer.

2 Turn the subassembly so you can see the area of the monitor board immediately behind the monitor connector.


3 Look for three red capacitors as pictured in this graphic.

Note:

The capacitors may not be present. See the graphic on the next page.


4 If three red capacitors are not present, replace the audio/monitor connection subassembly with part number 922-2996.

Additional Procedures 6500—Software Installation Errors and L2 Cache Identification

6500—Software Installation Errors and L2 Cache Identification

The symptoms during software installation on a Power Macintosh 6500 may appear as follows:• The installation is interrupted by a dialog box displaying

a message like this: “Unable to decompress file ‘xxxx’ because of a data mismatch error.” After dismissing the dialog box, the user may be able to continue installing or may only have the option to stop the installation, depending on the type of installer.

• During software installation, the system hangs (cursor arrow still moves), system freezes (cursor arrow does not move), or Type 10 errors are displayed requiring a reboot.


These symptoms may appear with any software, installer, and installation from CDs, floppy disks, Zip disks, or external hard drives.

Identifying Suspect Units

This problem is caused by a combination of a certain logic board manufacturer (OPC) together with a certain L2 cache in a small percentage of Power Macintosh 6500 computers that fall within this serial number range:



Recommended Action

If the symptom occurs on a 6500 computer in the specified serial number range, inspect the logic board for “OPC” printed along the edge. If the logic board has “OPC” on it, verify the cache is a compatible L2 cache DIMM. If the logic board is an OPC with an incompatible L2 cache, replace the incompatible L2 cache with part number 661-1477.

Identifying an OPC Logic Board

Here is how to positively identify an OPC logic board:

1 With the logic board connector closest to you, examine the right and left edges of the board.

2 Along the right or left side you may see the letters OPC.


Identifying L2 Cache DIMM

If the logic board is an OPC, follow these instructions to positively identify the L2 cache DIMM as compatible or incompatible:

1 View the back of the cache DIMM.

2 Notice that there is one larger chip and eight smaller chips. The eight smaller chips are organized in tow groups of four at each end of the DIMM.

3 Look at the markings on any one of the smaller chips. They will look similar to this:

IDT 74FST32384Q (This number is the identifying factor.)F9637BFU

If this number, not counting the Q or any other letters present, has five digits, it is compatible with OPC.


If this number, not counting the Q or any other letters present, has four digits, the cache is incompatible with an OPC logic board. Replace this L2 cache DIMM with part number 661-1477.

IDT 74FST3384Q (Use this number to identify a problem DIMM.)F9637BFU
